LEDERER 8a "IAUSSIG, 0F PHILADELPHIA, PENNSYLVANIA, A FIRM COMPRIS- IN G FRANK MONROE, NESSIE LEDERER, AND JULIUS TAUSSIG.

MIXING-MACHINE.

To all whom it may concern:

Beit known that I, FRANK MONROE, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Mixing-Machines, of which the following is a specification.

My invention relates to means, preferably power-driven, for mixing or stirring semiplastic, viscous, liquid, or other materials, and while my improved structure may be employed for many purposes, it has been particularly designed for use in the mixing or stirring of paint, and such mixing or stirring may be carried out in the can which the painter will use.

My invention includes means whereby I provide an adjustable can support for various sized cans, means wherebythe mixing or stirring members'are adjustable with respect to the can, a pivotal mounting for the bracket or support carrying the mixing or stirring members, means for driving the can in one direction and the mixing elements in another direction, and'other features of my invention more particularly described hereinafter, reference being had to the accompanying drawings in which:

Figure 1,is a plan view of one form of mixing or stirring structure embodying my invention.

Fig. 2, is a sectional elevation on the line II-II, Fig. 1.

Fig. 3 is an end-elevation, and

- Fig. 4, illustrates a detail of my invention.

The machine forming the subject of my invention may include. a base 1, having a step bearing 2, carrying a stub-shaft or spindle 3 for the reception of a-bevel gear wheel 4:,turning thereon, or if desired, the stub-shaft, or spindle 3 may be secured to the gear wheel and rotate in such step bearing; the latter being provided with means preventing removal therefrom,

This bevel gear wheel serves as a support for a can or receptacle, shown by dotted lines, in which materialto be mixed or stirred may be contained, and in order that such support may be adjustable, certain of the spokes 5 of the bevel gear Wheel 4 are Specification of Letters Patent.

Serial No. 304,744.

provided with radially adjustable dogs or stops 6, slidably mounted-in slots 7 of the spokes. A plurality of these dogs may have notched or serrated shoulders adapted to engage teeth 8 formed on the upper sides of the spokes and flanking the slots; said dogs being retained in their adjusted positions by bolts or screws 9 supporting plates 10, which engage the under side of the spokes at each side of the slots in the same.

Another dog, 6, may be arranged for adjustment back and forth along the slot of the spoke 5 in which it is mounted by means of a screw 11 having a polygonal head 12 whereby it may be readily turned by a wrench or other suitable means to move said dog toward and from a can or other receptacle mounted on the bevel gear wheel 4. If desired, the engaging lips of the dogs may be slightly undercut as indicated at 13, so as to prevent vertical movement of the receptacle as well as any movement tending to displace the same laterally.

Preferably,the axis of rotation of the receptacle should be the same as that of the gear wheel, and care should be taken in adjusting the dogs 6 and 6* of the gear wheel to see that such receptacle is centrally mounted with respect to the axis of rotation. Preferably, the base 1 carries a suitable guard 14 for the gear wheel 1 so that the latter will be protected and prevented from coming into contact with the operator or his clothing.

Adjacent the step bearing and, if desired, directly in line with the same on the base, is

' a pedestal support 15 for suitable gearing the gear wheels 21 an 22 are covered by a housing or guard 25, and the worm wheel is preferably covered or inclosed by a housing or guard 26.

As indicated in the drawings, the gear wheel 4 supporting the receptacle may be slightly larger than the gear wheel 17 so that movement of the receptacle will be at a speed slightly less than that of the gear wheel 17.

The stirring device comprises a plurality of arms 30, carried by a head 31, supported by a spindle or shaft 32, mounted above the receptacle and supported by a bracket 33. This bracket in turn carries a shaft 34, suitably journaled in an upper pivotally connected portion 15 of the standard or pedestal support 15, and additionally the bracket carries a guide rod 35 adapted to a slideway 36 at the top of'said pivoted portion 15.

The spindle 32, and the shaft 34, carry gear wheel 37 and 38, respectively, whereby motion of said shaft 34 may be imparted to the spindle 32, and thence to the mixing arms 30. The shaft 34 may be driven by a train of gears from the shaft 17 such train of gears being indicated at 40, 41,42 and 43, and so arranged that the direction of movement of the arms 30 will be opposite to the direction of rotation of any receptacle carried by the gear wheel 4. The gear 40 is preferably fixed to the hub of the gear wheel 17.

By providinganadjustable mounting or support for the bevel gear wheels 37 and 38, the arms 30 may be disposed in proper position with reference to any size receptacle supported by the gear wheel 4; the position of said arms with respect to such receptacle being preferably close to one side of the same so that proper mixing of the contents of the receptacle may be effected.

The guide rod 35 adapted to the slideway 36, is provided with a cam or screw locking lever 45 so that when the desired adjustment of the mixing or stirring arms is effected, the parts may be locked in the adjusted position. I

The portion 15 supporting the shaft 34 and rod 35 is pivotally connected at 46 to the pedestal support or standard 15, so that the mixing or stirring arms may be readily lifted from the mixing receptacle, and the rod 35 may have a hand-hold 35 to assist the operation. Generally the weight of the upper structure will be sufficient to hold the mixing arms in proper position but, if desired, means may be provided to lock the upper pivoted portion 15' to the pedestal 15.

When employed by a painter, for whose use my improved mixing device has been particularly. devised or designed, it frequently becomes necessary to screen out or separate the liquid portion of paint from the so-called paint skins. usual practice is to place a sieve or colander For this purpose, the' in the top of the receptacle and pass a brush around the same.

My improved mixing device is quite well adapted for brushing these paint skins, and in Fig. 4, I have shown an arrangement wherein the spindle or shaft 32 carries a collar 47 having an arm 48 to which a brush 49 may be secured by a set screw 50, and such brush is set preferably adjacent one wall of a sieve 51 in which the paint and paint skins are disposed and whichmay be set in a suitable receptacle 52 to receive the paint brushed loose from such skins.
